M51909P - 8-Step Bar Type Led Level Indicator

Download the M51909P datasheet PDF. This datasheet also covers the M51907P variant, as both devices belong to the same 8-step bar type led level indicator family and are provided as variant models within a single manufacturer datasheet.

General Description

The M51907P/M51909P is a semiconductor integrated circuit consisting of a Circuit designed for LEO level meters.

It is capable of bar type display for 8 LEOs according to a input level.

AC or DC signal can be inputted because of built-in superior half-wave rectification OP Amp.

Key Features

  • Built-in superior half-wave rectification OP Amp. Cut off frequency.
  • 500kHz (typ. ) Input offset voltage 2 mV (typ. ).
  • The LEO brightness can be adjusted by resistor. 2-25mA.
  • Range of supply volt.

MITSUBISHI LINEAR ICs M51907P M51909P a-STEP BAR TYPE LED LEVEL INDICATOR DESCRIPTION The M51907P/M51909P is a semiconductor integrated circuit consisting of a Circuit designed for LEO level meters. It is capable of bar type display for 8 LEOs according to a input level. AC or DC signal can be inputted because of built-in superior half-wave rectification OP Amp. Output is a cascade connection of a pair of LEOs, so current for display is half. Display level of the M51907P is logarithmical scale,+ 5, +2,0,-2,-5,-8,-13,-18 dB. The M51909P is a companion products to the M51907P, display level is linear scale, 156mV step. FEATURES • Built-in superior half-wave rectification OP Amp.
